通过稳态图来识别对机械机构的振动信号，用有理分式多项式法进行模态参数识别-By steady-state map to identify rational fraction polynomial method of mechanical vibration signal, modal parameter identification

是学习PCA特征提取的很好的学习资料，数据模型归一化，模态振动，Gabor小波变换与PCA的人脸识别代码。- Is a good learning materials to learn PCA feature extraction, Normalized data model, modal vibration, Gabor wavelet transform and PCA face recognition code.
